The MSCI tech index for Asia climbed 0.9 percent to ground not trod since early 2000, bringing its gains for the year to a heady 40 percent.

Yet the euro also benefited from buying against the yen, reaching its highest since February last year. It edged up 0.2 percent on the dollar to $1.1827 and back toward the 2-1/2-year high of $1.1845 struck on Monday.
